The Northern Lights appear all year round, but they are most impressive in the autumn months. They can also be seen in March and they "disappear" in the light summer nights.

Arsarnerit means ball games, and the sagas recount how the northern lights appear in the night sky when the souls of the dead play ball with walrus skulls.

The midnight sun is another magnificent Greenland phenomenon which is encountered north of the Arctic Circle. Daylight can be enjoyed round the clock, depending on how far north you are. For example, in Uummannaq, the midnight sun is present from the 16th of May to July 28th and during that time "normal" methods of working out what time it is are more or less useless. It is light around the clock.
